Take a look at how the NFL has evolved from its humble roots, and the efforts being made to ensure it continues to grow.

Bishop, who tore his hamstring as a member of the Green Bay Packers last year, started his first game of the season Sunday for the Vikings. Marvin Mitchell figures to take his starting job back from Bishop.

Minnesota is dealing with other injuries on defense. Safety Harrison Smith will undergo an MRI on his turf toe, according to Frazier, and rookie cornerback Xavier Rhodes has a sprained ankle.
